while I have worked in the telecom industry for the last decade in both a Linux/Unix and Cisco/Juniper troubleshooter capacity, I don't know enough about the mobile phone tech to give competent technical answer... but I will say that CDMA phones (Sprint, Verizon, Virgin, etc) have comparable hardware built into the phone that a GSM phone gets via a SIM card. The phone itself must be manufactured to exist on a specific CDMA network, that network needs to allow access to that uniquely IDed hardware (much like a computer MAC address) and then the phone's operating system must authenticate it's assigned account info.

While rooting my phone does allow me to use Wifi Hotspot and USB tether to gain internet access for other devices via 3G (or 4G once my area upgrades) without paying an extra $30 a month for it, the reason I do it is to remove Sprint's bloatware crap (Nascar, NFL, Sprint TV, etc) and run a leaner, faster, more efficient version of Android.

speaking of bloat ware there is an app called scavengr in the market that embeds itself to the point where its extremely hard to remove without some coding work..avoid it

You could probably remove it with a wipe and flash a new rom. I just looked it up and can't believe its still there with all the negative reviews.

That is the only thing bad about the play store. Lots of reallllllly good apps surrounded by junk

I just read an article on rooting Android phones in Maximum PC yesterday. Apparently, rooting a phone doesn't change the Verizon or other carrier programming that allows it to access a particular network. How does wiping a phone not erase the necessary access code that makes you a valid network user for, say Verizon that has no sim card?

Hey Dave...

I'm far from an expert but I'll explain it as best I can.

You have the SIM(not removable with certain carriers), and the eMMC. I think the SIM lives in a separate space than the eMMC. The eMMC contains all the partitions for the radio firmware, the boot loader and the OS.

When you root your phone, you generally unlock the eMMC, gain root access and then flash an engineering bootloader which makes it possible to flash a new OS.

The radio is hardwired to the specific frequency of your carrier, so even if you flash a new firmware to your radio (or root and change the OS), you can't change the band for which it was designed.

You can SIM unlock a phone and connect it to a carrier not in your band. The catch is you'll be limited to phone calls and, if you're lucky, Edge speeds. The SIM is different than the IMEI (on removable SIMS) but the carrier knows the unique serial number of the SIM and determines whether you have an account to be billed on their network.

Hope that makes sense.

I've kinda heard mostly opposite opinions regarding the nexus vs rezound, although if you prefer the HTC, I'm sure you could find someone that would be happy to trade.

Well let's use this as an example, right now I am around 3 people with a nexus. Quick poll results are battery sucks. All 3 of us charging our phone. 5 people have a rezound and all fairly happy with battery life.

I have to charge my phone about 3 times a day. Sure there are other factors if you are comparing the 2. But who cares if you are stuck on a charger all day.

There are definitely other considerations besides battery life but I see what you're saying. I wonder if the nexus's screen is just more power hungry or what, since I believe its battery has more capacity than the rezound's. You could always put a custom kernel on there that might help, or get the extended battery. I suppose the screen on the nexus is bigger, so it may draw more power. Although remember that with AMOLED screens you can save battery by using as much black as possible. I know there are blacked out google apps, etc. Just a thought.

I ALWAYS have my screen on the lowest setting with my gs2. Unless in broad ddaylight then I'll turn it up, Saves tons of battery. The usual people who complain about battery life are those who don't kill apps and have there screen so bright you need shades to read email

Most people believe killing apps makes battery life worse now.

I've read various opinions on task killers vs not using one at all and letting the phone manage the tasks. I do know that if I leave my camera in the background and don't exit back to the home page, my battery will drain at a higher rate. I guess it leaves the camera hardware functioning even in standby.

Most apps just stay in idle mode anyway and don't consume power. Memory is another concern entirely.

I was in Walmart the other day and went by to look at the phone kiosk. They have the Motorola Razr for $97 and the Samsung Stratosphere for 97 cents, upgrade or new contract. My wife likes the Stratosphere for the keyboard and I'm getting the Razr, but we are waiting for Verizon to announce the shared data plan first of the summer. I'm through paying for a data plan for each phone. $20 was bad enough, but $30 each is a deal breaker. I put my 2 cents worth in to the local Verizon manager about it and I'm thinking lots of people have done that. Wireless internet is available so many places that I stay well under 100mb. I can't see paying for 2gb or 4gb when my usage is consistently low ... unless it's a shared plan. Then, I'll bite.
